Charles Krauthammer has advocatedfor granting immunity to Lois Lerner in order to get her full testimony.

Krauthammer stated on Friday’s Special Report that the House Oversight Committee was right to decide that Lerner had waived her Fifth Amendment rights back in May by first declaring her innocence before the panel and then refusing to answer further questions. As the Democrats on the panel are “trying to do everything possible to slow down the investigation, pretend it doesn’t exist, pretend it is all over and solved,” he argued that Republicans should extend immunity to Lerner in order to move the investigation forward.

“If you ever want to crack the case and to get it back on track, you need somebody who will speak,” Krauthammer concluded.
